V INK-SAVING ATTACHMENT eel. EMBOSSING-PRESSES.

To all whom it may concern: I

Be it known thatI, CLYDE T. DEAN, a citizen of the United States,-residing atChicago, in the county ofCook and State of Illinois, have invented certain new and useful Improvements in Ink-Saving Attachments for Embossing-Presses, of which the following is a specification. I

The present invention relates; to an ink saving attachment .for embossing presses of that general character in which'the surplus ink is wiped from the surface of the die by a strip of 'paper,'and has for its object to provide a device of this character which embodies novel features ofconstruction whereby the ink can be recovered from the paper die wiping strip and the waste thereof avoided. i

Further objects of the invention are to provide a device of this character which is V comparatively simple and inexpensive in its construction, which can be readily applied to an embossing press without interfering in any manner withthe operation thereof, which elfectively softens and recovers the ink from the paper strip or web, and which will accommodate itself; automatically to either thick or thin deposits of ink upon the paper strip.

\Vith these and other objects in view, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims.

For a fullunderstanding of the invention, reference is to be had to the following description and accompanying drawing, in which V I 4 Q F igure 1 is a longitudinal sectional view through the rear end of an embossing press provided with an ink saving attachment constructed in accordance with the invention.

Fig. 2 is a rear elevation of the same with the waste roller removed. e y

in all the views ofjth'e'drawing by the same reference characters. V For the purpose of illustration "theiink saving .attachment' is shown .r-applied to peci fic ati on of Letters Patent.

a conventional construction of embossing press. The reference character A designates the mam frame of the embossing press,

the forward portion of the press being broken away and removed, since it forms no part of and has no direct relation to the invention. The paper web 1 which constitutes the wiping strip for the steel die or plate is unwound from a feed roll 2 at the rear end of the machine and finally wound upon a waste roll .3 whichis also arranged at the rear end of the machine and is dis. posed under .the feed roll 2. From the feed roll Qthe die wiping strip 1 passes under a steel roller 4 and over a steel roller 5 to the front of the embossing press. Suitable means for making an impression, such as the. die 50 .(see Fig. 3), is arranged at the front of the embossing press. A link, 51 is connected in the usual manner to the die or. printing surface 50 for moving the same, ink beingadapted to be spread overthe en: tire surface of the die so that it will fill the depressions formed bv the engraving, such depressions being indicated at 52. The ink is removed from the smooth face of the die bv the wiping strip 1, leaving the'ink in the depressions 52 to make an impression during the printing operation. The wiping strip 1 passes around a guide roller 53 at the front of the machine and is then carried under a pad 54 provided with a tightlystretched surface of suitable fabric 55. As the die passes under the pad 54: the upper surface of the die and the lower surface of the winin'g strip 1 are ti htly pressed together, with the'result that all of the ink on the plain.

surfaceof the die is wiped off onto the caper web 1. The conventional mechanism may be providedfor bringing a fresh por: tion of the wiping strip 1 in operative position across the face of the pad 54: each time,

the die 50 is to be wiped. After having been used to wipe the surplus ink from the steel die, the paper strip 1 passes rearwardly between a pair' of steel rollers 6 and 7 and: over a transverse guide rod 8 to the waste roll3. 'A considerable amount of ink isremoved from the die plate by this ink wiping I strip 1, and this ink is ordinarilywv-asted.

The ink saving attachment includes a roller 9 of some absorbent material such as feltwhi c'lrsupplies some'suitable absorbent such as benzinfrom a trough--10 to the surface of the roller 7. The lower portion-stills roller 9 runs in the liquid solvent 11 with which the trough 10 is partially filled so thatas the rollers revolve the benzin will be fed continuously to the roller 7 over which the die wiping strip 1 passes. A sufficient amount of the benzin or other solvent is thus supplied to the inky side of the wiping paper to soften the ink so that it can be rea transverse bar 15 which extends across the frame A of the embossing press and is secured thereto, at its extremities by suitable fastening means such as the bolts 16. Ar-

ranged above thebar 15 is a rod 17 which has the. ends thereof journaled within bearings 18 projecting from the bar. A set screw 19 is threaded in one of the bearings 18 for engagement with the rod' 17 to hold the same normally against movement,- Projecting laterally from one side of the rod 17 is, a series of prongs 20 which engage one end of a strip 21 of felt or similar material, the said felt strip havingthe opposite end thereof carried under the bar 15 and secured to one edge thereof by means of a clamping bar 22.

Suitable means such as, the screws 23. may be provided for holding the clamping bar in position and tightening or, loosening the' same. Any slack in the felt Strip 21 can be readily taken up by loosening the set screwv 19 and rotating the rod 17.

The yieldably mounted scraping blade 14:

is carried by a slide 24 which has opposite ends thereof'mounted within guides 25 secured to the sides of the main frame A of the embossing press; Coil springs 26 are arranged within the guides 25 and interposed between the ends of the slide 24and blocks 26, said blocks being engaged by adjusting screws 27 which are threaded within end pieces 28 appliedtothe guides. The scrapsion of the springs 25 c nbe adj s d t r gulate he-pres re f he scraping blade agains the pap r scrip a m y be f n necessary to pr duce h b t s lts previouslyso ten d-by-the benzi or other so ent e eived from the roller 7,. it will be readilyrseparated romth -p per Strip l y e sc ap ng blade 1% r a d. will dr p there. om; pon; inclined. plate or chute- 2 f om whieh: it r will a into a suitable cup crsreceptacleeflu The trough 10 for containing the solvent 11 may be supported in any suitable manner as by means of the bracket arms applied to opposite ends thereof and secured to the main frame A of the embossing machine. The inclined plate'or chute29 is mounted upon and secured to a transverse bar 32 connecting the suspending arms 31,-while the cup or receptacle may rest removably upon a pan or flanged plate 33 projecting rearwardly from the trough '10 and secured thereto. Such a construction admits of the inksaving attachment being readily mounted upon the conventional construction of embossing press without necessitating any material changes therein. The ink removed from the die plate by means of the strip of wiping paper will be first softened by applying some' suitable absorbent thereto and then scraped from the paper strip and collected in a cup or receptacle. The device operates automatically, requiring no attention on the part of the operator, and will recover. practically all of the ink removed from the die by the wiping paper, and which is ordinarily a total loss.
